Transesophageal Echocardiogram Flashcards
The LAD, diagonals, and septal perf orators make up the
LAD
What are the components of the left main coronary artery?
Left anterior descending
Circumflex
Ramus intermedius
The circumflex is composed of the
Circumflex and obtuse marginals
The components of the right main coronary artery are
RCA Acute/right marginals Atrioventricular nodal Posterior descending artery PL
The function of pulmonary circulation is to
Supply nutrients and circulation to lung tissue
The superior and inferior ______ usually arise directly from the
Left bronchial arteries
Thoracic aorta
There is a single right bronchial artery. It arises from the thoracic aorta at a common trunk with the _____ and the _______ on the left side
Right third posterior intercostal artery
Superior bronchial artery
The darkest blood in the body is in the
Coronary sinus
Coronary artery perfusion depends on
Left vs right ventricle timing
What is the route of coronary circulation?
Sinus of valsalva - coronary arteries - capillaries - coronary veins - coronary sinus
Equation for coronary perfusion pressure?
CPP = DBP - LVEDP
What is the formula for the concentration of arterial O2?
CaO2= (1.34 x Hgb x SaO2) + (PaO2 x .003)
What is the formula for delivery of arterial O2?
DaO2 = CO x CaO2
What is the formula for the volume of O2 consumption? What is this value normally?
VO2 = CO (CaO2 - CvO2)
3.5 L/min or 45 ml/kg/min
What is the equation for mean arterial pressure?
MAP = (SBP + 2DBP)/3 MAP = CO x SVR
